Tiny devices that harvest electrical energy from everyday tasks

Gabriel — Tue, 15 May 2012 18:31:55 +0000

Imagine charging your phone as you walk, thanks to a paper-thin generator embedded in the sole of your shoe. This futuristic scenario is now a little closer to reality. Scientists from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a way to generate power using harmless viruses that convert mechanical […]

Nanocrystal-coated fibers might reduce wasted energy

Gabriel — Fri, 20 Apr 2012 19:51:24 +0000

Researchers are developing a technique that uses nanotechnology to harvest energy from hot pipes or engine components to potentially recover energy wasted in factories, power plants and cars. “The ugly truth is that 58 percent of the energy generated in the United States is wasted as heat,” said Yue Wu, a Purdue University assistant professor […]

What happens when a drop of water falls on a lotus leaf? It’s not a philosophical question, but a natural phenomenon scientists have been studying, and trying to make sense of, for hundreds of years. The drop of water falls, bounces, and rolls away without trace – leaving the leaf clean and water repellant. Now scientists […]

The next generation of lithium ion battery

Gabriel — Sat, 15 Oct 2011 17:25:54 +0000

The design of today’s rechargeable lithium ion batteries limits the use of new technologies like electric cars and grid-scale energy storage because they do not store enough energy relative to their volume and weight – or, as researchers would say, their energy density is too low. Stanford researchers have used nanotechnology to invent a better […]

Hydrogen fuel available at petrol stations for consumers

Gabriel — Sat, 26 Feb 2011 18:28:55 +0000

Cella Energy was named the UK national winner for the Shell Springboard Awards 2011, for developing a technology which allows hydrogen to be stored in a cheap, practical way, bringing the prospect of hydrogen fueled cars one step closer to reality. Hydrogen, which produces only pure water when burned, is considered an ideal solution to […]

International Collaboration Boosts Nanotechnology Research

Gabriel — Sat, 11 Dec 2010 19:32:16 +0000

Despite their initial focus on national economic competitiveness, the nanotechnology research initiatives now funded by more than 60 countries have become increasingly collaborative, with nearly a quarter of all papers co-authored by researchers across borders. Researchers from the two leading producers of nanotechnology papers — China and the United States — have become each nation’s […]

How Nanotechnology has the Ability to Solve Problems

Adrian — Thu, 18 Nov 2010 23:00:27 +0000

Your cell phone may one day be powered by a nanoprotein extracted from spinach. Leafy vegetables use photosynthesis to convert solar energy in order to grow, said Hongda Chen, a national program leader at National Institute of Food and Agriculture at the United States Department of Agriculture. By studying the plant’s Photosystem I, nanoscale protein […]

Silk Technology Offers Solutions for Medicine and Electronics

Adrian — Thu, 05 Aug 2010 03:52:06 +0000

An ancient fiber could soon be spun into cutting edge technology. Recent discoveries and new processing techniques have shown that silk can offer innovative solutions in medicine and electronics. For centuries, silk has been celebrated for both its durability and delicacy. However, this fiber—made largely from the cocoons of the mulberry silkworm, Bombyx mori—hasn’t seen […]
